Which tendon is responsible for dorsiflexion and stabilization of the great toe?

The tendon responsible for dorsiflexion and stabilization of the great toe is the Extensor Hallucis Longus. This muscle originates from the fibula and inserts into the distal phalanx of the great toe. Its primary functions include not only dorsiflexion of the great toe but also assisting with dorsiflexion of the ankle joint. This means it plays a crucial role in lifting the toe while walking or running, which helps in maintaining the balance and stability of the foot during movement.

In addition to this, the Extensor Hallucis Longus helps stabilize the great toe, which is essential for activities that require precise foot placement and coordination, such as sports or walking on uneven surfaces. This stabilization is particularly important in preventing injuries and ensuring efficient gait mechanics.

The other tendons mentioned, while involved in foot movement, do not specifically stabilize the great toe nor are they primarily responsible for its dorsiflexion. For instance, the Flexor Digitorum Longus and Flexor Hallucis Longus primarily contribute to plantarflexion and flexion of the toes, whereas the Extensor Digitorum Longus is more involved with extending the other toes rather than the great toe specifically.
